Georges de La Tour was a prominent French painter whose work is an excellent representation of several key principles of Baroque art. Here’s how his work embodies these principles:

1. Chiaroscuro: La Tour is renowned for his use of chiaroscuro, a technique that contrasts light and dark to give a dramatic effect to his paintings. This technique is a hallmark of Baroque art, providing a sense of three-dimensionality and emotional intensity. In many of his works, La Tour creates strong contrasts by depicting candle-lit scenes where subjects emerge from deep shadows. A famous example is "The Penitent Magdalene," where the light source highlights key elements while much of the rest is enveloped in darkness.

2. Realism and Naturalism: Unlike the idealized depictions of earlier periods, Baroque art often focused on realistic portrayals and emotional expression. Georges de La Tour's paintings are characterized by their detailed realism and subtly portrayed human emotions. He often depicted simple, everyday subjects or scenes with a remarkable sense of serenity and stillness, yet imbued with profound humanity and introspective moods.

3. Dramatic Effect: Baroque art is known for its drama and movement. While La Tour's works are more subdued in activity compared to some of his Baroque contemporaries, the drama in his pieces often comes from the lighting and the deeply introspective expressions of his subjects. This theatrically focuses the viewer’s attention and evokes contemplation.

4. Religious Themes: Baroque art heavily centered around religious themes, driven in part by the Counter-Reformation's emphasis on creating emotional engagement with faith. La Tour painted many religious subjects, treating them with a unique sense of quiet introspection that wasn't about explosiveness but rather gentle, contemplative spirituality.

Overall, Georges de La Tour captured the essence of Baroque art not with the grandeur and opulence often associated with the style but through intimacy, light manipulation, and emotional depth, making his works timeless and deeply thought-provoking.
